Calibre is an e-Book management tool that is popular among e-Book lovers. Calibre provides free and one-stop solutions to all your e-Book needs. It can be used to manage your e-Book collection, convert the format of e-Books, download magazines and news from the web, backup your library, and more.

For e-readers seeking to remove the DRM protection, Calibre is a good choice.

This program, being open source, allows you to develop and personalize it to meet your needs.

For all the advantages, Calibre is not all perfect. The Calibre tool can not remove e-Book DRM directly. You need to install a removal plugin, DeDRM, to help you.

The DRM removal tool Calibre and its 5 alternative windows are briefly introduced in the above. If you still have no idea which one to use, have a look at the table below and let’s make a comparison between these programs.

Under other attributes for comparing, they show different performance. All the group, except Leawo Prof. DRM, supports e-Books only, while Leawo also works for audiobooks.
